Buying property in Sardinia is often a mix of excitement and fear. The island offers beaches, countryside and towns that are hard to match elsewhere in the Mediterranean, but the legal and practical side can feel opaque—especially if you are buying from abroad. In daily practice, the same mistakes appear again and again when foreign buyers decide to “keep it simple” or to rely on partial information. Understanding these patterns is the first step to avoiding them.
This guide collects the most common mistakes seen in Sardinian property transactions and shows how a different approach—combining local legal due diligence, realistic expectations and the right sequence of steps—can turn a risky move into a controlled project.
Mistake 1: Treating the Preliminary Contract as a Formality
One of the biggest misconceptions is the idea that the preliminary contract is a soft, reversible step and that the “real” commitment happens only at the notary. In Italian law it is the opposite: the preliminary is a binding contract that fixes price, deadlines, penalties and what happens if either party defaults. Signing it lightly, based on a template or an agent’s draft, can lock you into obligations that are difficult and expensive to escape if problems emerge later.
The cure is simple but requires discipline: full legal due diligence and legal review of the preliminary before signing, not after. That means letting your lawyer check ownership, planning status, debts and contractual clauses first, then integrating the findings into the text you sign. The final deed at the notary should be the end of a process already cleaned and negotiated, not the moment where hidden risks surface.
Mistake 2: Assuming the Notary Will Do All the Checks
Another recurring mistake is believing that the notary is responsible for checking everything about the property. In reality, the notary’s role is to verify identity, ownership and some key legal aspects, then to formalise and register the transfer; the notary is not a substitute for a buyer’s lawyer and does not perform exhaustive due diligence on planning history, cadastral coherence, condominium debts or practical risks.
Relying solely on the notary often means that issues like unpermitted extensions, landscape infractions, hidden condo debts or unclear boundaries are not fully explored. A dedicated real estate lawyer, working alongside the notary, goes deeper into these areas and reports to you—not to both parties—so that your decisions are based on a complete picture.
In addition, the notary usually appears in the transaction only at a very late stage, when a binding preliminary contract has already been signed and significant deposits have already been paid. At that point, even if the notary’s checks bring problems to light, you are often legally and financially committed, and recovering what you have already paid may require litigation rather than a simple adjustment of the deal.
Mistake 3: Falling in Love with a Property Before Checking the Legal Reality
Emotional attachment is natural when buying in Sardinia. It is easy to fall in love with a view, a stone house or a stretch of countryside and to mentally move in before reading a single document. The problem is that certain types of properties—seaside villas, historic apartments, rural houses—are exactly those where planning history and cadastral records are most likely to hide surprises.
The safest sequence is to allow yourself to like a property, but to suspend serious commitment until the checks are complete. That means using offers and reservation forms carefully, avoiding large non‑refundable deposits tied to deadlines you cannot control, and being ready to walk away if the legal reality contradicts the dream. In a market as varied as Sardinia, there is almost always another option; there is not always a way to fix a badly chosen one.
Mistake 4: Underestimating Condo Debts and Internal Rules
For apartments and villas in complexes, the focus is often on the unit itself: size, view, renovation level. Buyers rarely ask about the condominium’s finances and rules until after completion. Yet unpaid condo debts can become your problem once you become owner, and internal regulations can restrict rentals, uses of common areas and even the possibility to enclose terraces or change external elements.
A good due diligence includes obtaining statements from the administrator on financial status, reviewing recent meeting minutes and reading the building’s internal regulations. This reveals upcoming extraordinary works, disputes between owners, restrictions and patterns of non‑payment that would otherwise catch you off‑guard. In practice, avoiding one bad building can matter as much as choosing the right flat.
Mistake 5: Ignoring Landscape and Coastal Protections
Many of the most beautiful properties in Sardinia are also the most regulated. Coastal belts, scenic viewpoints and certain rural areas fall under strict landscape and environmental protections that dictate what can be built, extended, renovated or regularised. Buyers who assume that “everything can be fixed” if needed often find that the law simply does not allow it, no matter how much they are willing to spend.
Avoiding this mistake requires integrating landscape checks into standard due diligence, not treating them as a specialist extra. It also means aligning your renovation or expansion plans with legal reality before you buy. If a key part of your project—adding a pool, enclosing a veranda, building a guest annex—is impossible under current rules, it is better to know and decide accordingly than to discover it after completion.
Mistake 6: Trying to Manage Everything from Abroad Without a Local Team
With online listings and video calls, it is tempting to think that buying in Sardinia from abroad can be done entirely by remote control, with occasional help from whoever happens to answer your emails. In practice, the transactions that go wrong most often are those where no single local team has the full picture; agents, notaries, translators and technicians each handle a small piece, but nobody is responsible for connecting the dots.
Working with a coordinated team—lawyer, and, if you wish, buyer’s agent—means that someone on the ground sees the whole file and can warn you when timelines, promises or documents do not align. It also means that your time in Sardinia, if you visit, is used for targeted viewings and closing, not for firefighting unexpected problems.
Mistake 7: Believing That All of Sardinia Is the Same
From an external perspective, Sardinia can look like one homogeneous destination. In reality, Alghero, Costa Smeralda, Olbia, Castelsardo, rural Gallura and southern coastal towns are different markets with different dynamics, risks and opportunities. Applying the same expectations and strategy everywhere—on price, rental potential or liquidity—often leads to disappointment.
A more intelligent approach is to treat “where to buy in Sardinia” as a separate decision from “whether to buy in Sardinia”. That means comparing areas based on your priorities: year‑round life vs. peak‑season use, prestige vs. value, coast vs. countryside, rental focus vs. pure lifestyle. Only then does it make sense to shortlist properties and begin detailed checks.
